HOSE-NOZZLE! SPEOIFIGATIONTormingpart'of Letters Patent No. 6C 9,845,dated March 12, 1901. Application filed August 23, 1900. Serial No.27,795. (No model.)

To (all, w/tom z t viz/any concern: Be it known that I, JoHN H. MELAVIN,Cambridge, in the county of Middlesex and State of Massachusetts, haveinvented certain new and useful Improvements in Hose- Nozzles, of whichthe following is a specifica tion.

This invention relates to nozzles for regulating the flow of water froma hose, and is particularly adapted for use in Washing carriages orwoodwork, where rapid changes in the velocity and shape of the jet arerequired. The invention consists in the improvements which I will nowproceed to describe- I 5 and. claim.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a longitudinal section of a nozzle embodying myinvention. Fig. 2 represents a perspeczo tive view showing the method ofthe nozzle by one hand. The same reference charactersindicate the sameparts in both the figures.

Referring to the drawings, the nozzle com- I prises a rigid metallicsection a, having at one end an internally-threaded portion Z, intowhich is screwed the threaded coupling of a hose 6, and at its other enda threaded portion m, to which is attached the flexible delivery-section70, which has body portion of rubber or other elastic material and aninternally -threaded metallic bushing is, detaciiably engaging theexternally-threaded portion 1%. The rigid section a is divided 5 intotwo parts by a partition 12, through which the water may flow by way ofan opening c, which is surrounded by a valve-seat and is normally closedby a valve d, that is held against its seat by the pressure of the waterin the hose and by a spiral sp'ringf. The thrust of the springf issustained by a plug j, which is screwed into the section a and may heremoved to allow-the removal of the spring f and valve d. To" allow theflow of water through the nozzle,the valve 01 is forced away from itsseat-by pressure of the hand of theoperator against the buttonor'push-knob h, which acts on the valve through a stem 9-, which passesinto the section a through a go stufiingbox'p and is attachedi'at itsopposite endsto the knob and the valve.

operating The outer surfaces of the knob h and the section a arepreferably covered with rubber to guard against scarring of the articlesoperated on through carelessness of the operator. I

In using this device the nozzle is held in such a way that the knob maybe pressed inward by the ball of the thumb, while the flexible tip ofthe nozzleis held betweenthe thumb and forefinger of the same hand, asshown by Fig. 2. By pinching the-end of/the portion In the outlet may becontracted, thusinereasing the velocity of the jet and altering itsshape and character. At the same time the pressure on the knob maybevaried to alter the pressure of water flowing to and through theflexible delivering-section, this change being efiected by a'portion ofthe same hand the fingers of which are employed for vary- 7o ing thesize or shape of the outlet. Therefore the user may employ one hand foranother. purpose, such' as turning a wheel of the carriage being washed,and with the other hand not only cause the water to flow full '75 forceor stop or vary between these points, but also change the character. orshape of the jet,whether the latter is slight or on full.

force. When the nozzle isreleased, the valve automatically closes andstops the flow of wa- [.er. Ordinarily for washing carriages and thelike a flexible hose without a nozzle is used, the variations in shapeand velocity of the jet being caused, as in this case, by pinching theend of the hose; but when, as often happens, the end ofthe hose isdropped the water continues to flow uselessly and consid erable wasteresults, whichis prevented by the use of a device such as the onedescribed. On, the other hand, however, none of the nozgo zle's now inuse having means forshutting off the water are suitable for the purposeindicat-ed, as the water issues from them in their difierent adjustmentswith either too much or too little force and the jet is too compact ortoo finely divided as spray. In addition the changes in the character ofthe jet cannot'be made with sufiicient ease or rapidity.

I claim- 1. A nozzle having two liquid-controlling loo means, one forvarying the pressure of water.

on its way to the outlet of the nozzle'iand the other for varying theshape or character of the jet, the said two controlling means beingthrough one side of the rigid section and provided at its outer end witha push-knob, and a flexible section detachably secured to the rigidsection and having a compressible 'de;

livering end, the relative positions of the push-knob and thecompressible deliveringend being such that the push-knobmay be pressedinwardly by the ball of the thumb and the delivering end compressed bythe thumb and forefinger 0f the'hand holding the nozzle, substantiallyas described Intestimony whereof I have affixed my signature in presenceof two Witnesses.
